Hydrogel scar patch for softening and fading scars

Abstract

The invention relates to a hydrogel scar patch for softening and fading scars. The invention is characterized in that: besides serving as a drug delivery platform, a gel plaster also can treat scars; it has good therapeutic effects on scars, can soften and fade scar tissues, and can flatten scars. The principle of the hydrogel scar patch is based on a gel plaster's hydrophilic matrix, which has the characteristics that: 1. the hydrophilic gel matrix has a high moisture content up to over 70%, can actively hydrate scar skin, and the hydration degree is high, thus being more conducive to softening and flattening of scars; and 2. the hydrophilic gel matrix generates mechanical compression on skin surfaces, thus exerting a mechanical pressure on scar bodies.

Description

technical field [0001] The present invention relates to a kind of hydrogel scar plaster with hydrogel as the main component, which is applied to the treatment of various scars. , Analgesic effect. Background technique [0002] Scars are the inevitable result of healing of various wounds, but if the healing is insufficient or excessive, scars will be formed, and if the scars continue to proliferate, hypertrophic scars can occur. According to the degree of damage caused by various injury factors and the physique of the injured, the following types of scars can be caused: superficial scars, atrophic scars, sunken scars, hypertrophic scars, keloids, especially for people with scar constitution, scars Especially obvious. Scars will bring great inconvenience to patients, such as hypertrophic scars caused by burns, which can cause local itching, pain, and even dysfunction, which seriously troubles patients. The prevention and treatment of scars has always been a difficult proble...

Problems solved by technology

[0004] However, the above-mentioned silicone gel scar stickers have the following problems: 1. Weak hydration: First, this type of product does not contain moisture, and its hydration is blocked by silicone gel products through skin moisture evaporation, and the moisture is passive. Retained in the scarred skin, the hydration effect is limited; secondly, due to some serious injuries, such as third-degree burns, skin sweat glands, etc., the water evaporation is limited, and the hydration effect is greatly weakened; 2. Difficult to combine drugs: silicone gel It is difficult to combine in the scar patch, and it contains other ingredients that can inhibit scars, and the combination of drugs can improve the curative effect

Although the silicone gel membrane has a certain ability to pass through water vapor, the molecular weight of the drug or other effective ingredients for scars is usually dozens or hundreds of times that of the water molecule, so the permeability of the silicone gel to the membrane drug is even Yes, but very limited, therefore, silicone gel film is not an ideal carrier for transdermal absorption
